worth of not less than Nine Million Dollars ($9,000,000.00).

        3.      CHARACTER OF OBLIGATIONS.

                (1)     This is an absolute, continuing and unconditional
        guaranty of payment and not of collection and if at any time or from
        time to time there is no outstanding Guaranteed Indebtedness, the
        obligations of Guarantor with respect to any and all Guaranteed
        Indebtedness incurred thereafter shall not be affected. This Guaranty
        and the Guarantor's obligations hereunder are irrevocable and, in the
        event of Guarantor's death, shall be binding upon Guarantor's estate
        pursuant to PARAGRAPH 10 herein. All of the Guaranteed Indebtedness
        shall be conclusively presumed to have been made or acquired in
        acceptance hereof. GUARANTOR SHALL BE LIABLE, JOINTLY AND SEVERALLY,
        WITH BORROWER AND ANY OTHER GUARANTOR OF ALL OR ANY PART OF THE
        GUARANTEED INDEBTEDNESS.

                (2)     State Farm may, at its sole discretion and without
        impairing its rights hereunder, (I) apply any payments on the Guaranteed
        Indebtedness that State Farm receives from Borrower or any other source
        other than Guarantor to that portion of the Guaranteed Indebtedness, if
        any, not guaranteed hereunder and (II) apply any proceeds it receives as
        a result of the foreclosure or other realization on any collateral for
        the Guaranteed Indebtedness to that portion, if any, of the Guaranteed
        Indebtedness not guaranteed hereunder or to any other indebtedness
        secured by such collateral.

                (3)     Guarantor agrees that its obligations hereunder shall
        not be released, diminished, impaired, reduced or affected by the
        existence of any other guaranty or the payment by any other guarantor of
        all or any part of the Guaranteed Indebtedness and Guarantor's
        obligations hereunder shall continue until State Farm has received
        payment in full of the Guaranteed Indebtedness.

                (4)     Guarantor's obligations hereunder shall not be released,
        diminished, impaired, reduced or affected by, nor shall any provision
        contained herein be deemed to be a limitation upon, the amount of credit
        which State Farm may extend to Borrower, the number of transactions
        between State Farm and Borrower, payments by Borrower to State Farm or
        State Farm's allocation of payments by Borrower.

        such financial condition or collateral as an inducement to enter into
        this Guaranty; and

        effect upon the financial condition of Guarantor or upon such security
        or might cause a default under any of the Loan Documents, (ii) any claim
        or controversy which might become the subject of such litigation or

        Borrower or any other person or entity, whether by separate action or by
        joinder.

        COVENANTS OF GUARANTOR SET FORTH HEREIN, GUARANTOR HEREBY FURTHER WAIVES
        AND RELEASES ALL CLAIMS, CAUSES OF ACTION, DEFENSES AND OFFSETS FOR ANY

        whether occurring by reason of law or otherwise; (iv) the taking or

                (2)     This Guaranty shall continue to be effective or be
        reinstated, as the case may be, if at any time any payment of all or any
        part of the Guaranteed Indebtedness is rescinded or must otherwise be
        returned by State Farm upon the insolvency, bankruptcy or reorganization
        of Borrower, Guarantor, any other guarantor of all or any part of the
        Guaranteed Indebtedness, or otherwise, all as though such payment had
        not been made.

                (3)     In the event Borrower is a corporation, joint stock
        association or partnership, or is hereafter incorporated, none of the
        following shall affect Guarantor's liability hereunder: (i) the
        unenforceability of all or any part of the Guaranteed Indebtedness
        against Borrower by reason of the fact that the Guaranteed Indebtedness
        exceeds the amount permitted by law; (ii) the act of creating all or any
        part of the Guaranteed Indebtedness is ultra vires; or (iii) the
        officers or partners creating all or any part of the Guaranteed
        Indebtedness acted in excess of their authority. Guarantor hereby
        acknowledges that withdrawal from, or termination of, any ownership
        interest in Borrower now or hereafter owned or held by Guarantor shall
        not alter, affect or in any way limit the obligations of Guarantor
        hereunder.

        8.      ACTIONS AGAINST GUARANTOR. In the event of a default in the
payment or performance of all or any part of the Guaranteed Indebtedness when
such Guaranteed Indebtedness becomes due, whether by its terms, by acceleration
or otherwise, Guarantor shall, without notice or demand, promptly pay the amount
due thereon to State Farm, in lawful money of the United States, at State Farm's
address set forth in SUBPARAGRAPH 1(I) above. One or more successive or
concurrent actions may be brought against Guarantor, either in the same action
in which Borrower is sued or in separate actions, as often as State Farm deems
advisable. The exercise by State Farm of any right or remedy under this Guaranty
or under any other agreement

<PAGE>

or instrument, at law, in equity or otherwise, shall not preclude concurrent or
subsequent exercise of any other right or remedy. The books and records of State
Farm shall be admissible in evidence in any action or proceeding involving this
Guaranty and shall be PRIMA FACIE evidence of the payments made on, and the
outstanding balance of, the Guaranteed Indebtedness.

        9.      PAYMENT BY GUARANTOR. Whenever Guarantor pays any sum which is
or may become due under this Guaranty, written notice must be delivered to State
Farm contemporaneously with such payment. Such notice shall be effective for
purposes of this paragraph when contemporaneously with such payment State Farm
receives such notice either by: (a) personal delivery to the address and
designated department of State Farm identified in SUBPARAGRAPH 1(A) above, or
(b) United States mail, certified or registered, return receipt requested,
postage prepaid, addressed to State Farm at the address shown in SUBPARAGRAPH
1(A) above. In the absence of such notice to State Farm by Guarantor in
compliance with the provisions hereof, any sum received by State Farm on account
of the Guaranteed Indebtedness shall be conclusively deemed paid by Borrower.

        10.     DEATH OF GUARANTOR. In the event of the death of Guarantor, the
obligations of the deceased Guarantor under this Guaranty shall continue as an
obligation against Guarantor's estate as to all of the Guaranteed Indebtedness.
The terms and conditions of this Guaranty, including without limitation the
consents and waivers set forth in PARAGRAPH 6 hereof, shall remain in effect
with respect to the Guaranteed Indebtedness in the same manner as if Guarantor
had not died.

        11.     NOTICE OF SALE. In the event that Guarantor is entitled to
receive any notice (which shall be given to the address listed on the signature
page hereof) under the Uniform Commercial Code, as it exists in the state
governing any such notice, of the sale or other disposition of any collateral
securing all or any part of the Guaranteed Indebtedness or this Guaranty,
reasonable notice shall be deemed given in the manner set forth in SECTION 8.1
of the Deed of Trust and Security Agreement executed by Borrower to the benefit
of State Farm dated of even date herewith.

        12.     WAIVER BY STATE FARM. No delay on the part of State Farm in
exercising any right hereunder or failure to exercise the same shall operate as
a waiver of such right. In no event shall any waiver of the provisions of this
Guaranty be effective unless the same be in writing and signed by an officer of
State Farm, and then only in the specific instance and for the purpose given.

        13.     SUCCESSORS AND ASSIGNS. This Guaranty is for the benefit of
State Farm, its successors and assigns. This Guaranty is binding upon Guarantor
and Guarantor's heirs, executors, administrators, personal representatives and
successors, including without limitation any person or entity obligated by
operation of law upon the reorganization, merger, consolidation or other change
in the organizational structure of Guarantor.

        14.     COSTS AND EXPENSES. Guarantor shall pay on demand by State Farm
all costs and expenses, including without limitation all reasonable attorneys'
fees, incurred by State Farm in

<PAGE>

connection with the preparation, administration, enforcement and/or collection
of this Guaranty. This covenant shall survive the payment of the Guaranteed
Indebtedness.

        15.     SEVERABILITY. If any provision of this Guaranty is held by a
court of competent jurisdiction to be illegal, invalid or unenforceable under
present or future laws, such provision shall be fully severable, shall not
impair or invalidate the remainder of this Guaranty and the effect thereof shall
be confined to the provision held to the illegal, invalid or unenforceable.

        16.     NO OBLIGATION. Nothing contained herein shall be construed as an
obligation on the part of State Farm to extend or continue to extend credit to
Borrower.

        17.     AMENDMENT. No modification or amendment of any provision of this
Guaranty, nor consent to any departure by Guarantor therefrom, shall be
effective unless the same shall be in writing and signed by an officer of State
Farm, and then shall be effective only in the specific instance and for the
purpose for which given.

        18.     CUMULATIVE RIGHTS. All rights and remedies of State Farm
hereunder are cumulative of each other and of every other right or remedy which
State Farm may otherwise have at law or in equity or under any instrument or
agreement, and the exercise of one or more of such rights or remedies shall not
prejudice or impair the concurrent or subsequent exercise of any other rights or
remedies.

        19.     GOVERNING LAW. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

        20.     VENUE. Federal and state courts within HARRIS COUNTY, TEXAS
shall have jurisdiction over any and all disputes arising under or pertaining to
this Guaranty and venue for any such disputes shall be in the county where the
Premises is located.

        21.     COMPLIANCE WITH APPLICABLE USURY LAWS. Notwithstanding any other
provision of this Guaranty or of any instrument or agreement evidencing,
governing or securing all or any part of the Guaranteed Indebtedness, Guarantor
and State Farm by its acceptance hereof agree that Guarantor shall never be
required or obligated to pay interest in excess of the maximum nonusurious
interest rate as may be authorized by applicable law for the written contracts
which constitute the Guaranteed Indebtedness. It is the intention of Guarantor
and State Farm to conform strictly to the applicable laws which limit interest
rates, any of the aforesaid contracts for interest, if and to the extent payable
by Guarantor, shall be held to be subject to reduction to the maximum
nonusurious interest rate allowed under said law.

        22.     DESCRIPTIVE HEADINGS AND DEFINITIONS. The headings in this
Guaranty are for convenience only and shall not define or limit provisions
hereof. All capitalized terms used herein, but not defined herein, shall have
the same meaning as set forth in the Promissory Note.

        23.     GENDER. Within this Guaranty, words of any gender shall be held
and construed to include the other gender.
